Have you ever wondered about the GPS signal-tracking capabilities ‘L1P, L2E'? One of our readers asked our specialist for an explanation, and this is what he replied. We rece...

Looking back over the past 30 years, it’s hard to believe just how far we’ve come in such a relatively short space of time. Geomatics students in the mid-1980s were exp...

Currently there are four global navigation satellite systems (GNSSs) available: GPS, Glonass, BeiDou and Galileo. The satellites of these systems are used for positioning, and the...

Fit-for-purpose approaches to land administration have been tested in Kenya, with a focus on the provision of land titles with inclusiveness for all in an approach that is affordab...

Deformation monitoring of glaciers is of great value to scientists with an interest in climate change. Due to the slow movements of glaciers, a semi-permanent deformation system is...

Nepal is prone to earthquakes and throughout the centuries the country’s capital city, Kathmandu, has been regularly struck by earthquakes which appear to have similar epicen...

Today GNSS is widely used in Oman. High and homogeneous quality of GNSS positioning requires a geocentric datum attached to the International Terrestrial Reference Frame of which t...

A two-week field trip to Iceland – that was all they were told beforehand. After one year of studying at Delft University of Technology, MSc students headed towards this geodetical...

With so many off-the-shelf GNSS solutions is there still room for innovation? Joël van Cranenbroeck thinks so. One such solution could be based on multiple antennas. But remem...

What will the new GNSS signals bring to the user of high-precision receivers? This article provides a brief overview of what users can expect from GNSS systems that are currently i...

Geomatics is not primarily aimed at investigating the causes and physical phenomena related to earthquake events. It has, however, over recent years established a fundamental role...

Knowing where one is inside an office, shopping centre or other giant building, and how to get to where one wants to be, is key for fire fighters, medical personnel and other resc...

I enjoyed all the discussion and speculation at the GSDI 12 Conference in Singapore last October over what ‘SDI 2.0’ would look like. There were also exciting ideas a...

A fire-fighter can pretty easily get lost and disorientated when surrounded by smoke in the middle of the night. GPS navigation is great, but not for working inside buildings beca...

It's no secret that GPS systems have changed surveying. To keep pace with industry, international educational systems need to teach students how to use GPS systems and modern surve...

GeoEye-1 Imagery for GoogleGeoEye has started delivering Google with high-resolution, colour satellite imagery from its newest satellite. The GeoEye-1 satellite images currently hi...

Prediction of earthquakes using GPS analysis remains an unresolved but important problem. Pre-signals -changes in area measured by triangular networks of GPS receivers- were examin...

In my March editorial I took you along on my adventure with fellow conference participants as we got lost in Prague. Despite having to hand a GPS device, we ended up at the wrong...

A virtual reference station (VRS) was introduced in Malaysia employing real-time kinematic (RTK) equipment. The project for updating the coordinate system, designated Coordinated C...

From entrepreneurs to incorporation to becoming publicly traded and now ISO certified, Hemisphere GPS has evolved into a major player in the design and manufacture of precision GPS...
